All we have to do is find out what multiple of 28 has all the same digits.
:
Acually between 100 and 1 million there is not that many. We know the number has to be even, no zeros obviously. Get a calculator and start with 222/28, then 444/28, etc. I got to 444444 and found that 28 goes evenly into it, 15873 times so this many tiles cost $4,444.44.
